Do most operating systems have a preferred file system?

Most operating systems indeed support multiple file systems, making the first choice the correct answer. This flexibility allows users to select the most appropriate file system for their specific use cases, whether they prioritize performance, data integrity, or compatibility with certain storage devices.

For example, Linux can work with ext4, XFS, Btrfs, and many others, while Windows typically uses NTFS but also supports FAT32 and exFAT. This capability is crucial in diverse scenarios, such as using external drives formatted in different file systems or maintaining compatibility with other operating systems.

The other choices do not accurately represent the nature of modern operating systems. While it might seem that operating systems are indifferent to file systems, this overlooks their active support for various types. Saying that they typically use only one file system would incorrectly imply a limitation that does not exist in practice. Lastly, relying solely on external applications for file management also ignores the built-in file management capabilities that are integral to how operating systems function.
